BALL.

SPECIFICATION forming part of vl'aetters; Patent No. 700,144, dated May 13, 1902.

Application led April 15., 1902.`

To @ZZ whom it 'may conccrmv Be it known that I, ELEAZER KEMPSHALL,

' a citizen of the United States, residing in Bos-v ton, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Golf-Balls, of which the following is a specification. i

This invention relates to playing-balls, and especially to those used in the game of golf; and its object is to produce at low cost balls well adapted to the requirements of the game.

In the drawings forming part of this speciiication, Figure l'illustrates the parts assembled prior to compressing 'the core of the ball and welding shell-segments thereon. Fig. 2, which is partly in section, shows the condition of the ball'j ust prior to the iinal heating and compression thereof. Fig. 3 illustrates ahollow sphere used for the core of the ball. Fig. e shows a portion of a strip used in making the casing of theA ball. Eig. 5 illustrates the last stage in forming the ball, this figure being partly in section.

Similar parts in the drawings are indicated by similar characters yof reference.

For the core I use a thick-walled and substantial sphere A, of solid soft rubber, said sphere being hollow, as at B.' Over this spherl ical shell I place hemispherical cups C and D," of plastic material, such as cell uloid or g'utta percha, preferably the latter,'rand I place' the whole between heating and compressing dies' F and G, which are then brought together with great force. Y The rubber spherical shell'A in its originalcondition is considerably oversize; but byv the action of the dies the cups are forced together over said shell and caused to Weld at their edges, thus forming the ball, consisting of a gutta-percha shell or cover and a rubber filling or core, the latter reduced in bulk.

One of the mainpurposes of my invention is to force the rubber spherical shellA into a small compass or cause it to collapse, as at A', Fig. 2, thus compressing and distorting the rubbergwhichis putin an abnormal condition throughout, and hence imparts to the ball phenomenal flying power, both on account of its increasedresilience and also because of its great expansive tendency or its tendency to Serial No, 103,009. (No model.)

`recover its normal size or form, which serves instantly to restore the spherical shape of the ,coverC' when the latter is distorted by a blow.

It will be seen that the distortion of the core occurs in substantially radial directions, the core being reduced in diameter by the die action.

I provide in the original rubber shell A an air-vent II, so as to permit the rubber shell to be compressed to form a substantially solid sphere or one without a central hollow space, as at Figs. 2 and 5'.

Over the gutta-percha cover C', Fig. 2, I wind tightly strips consisting of Celluloid J,

faced or lined with fabric Kythe' Celluloid preferably being in a partially-cured condition and the strips being preferably caused to adhere where they cross by' .cexnenting or otherwise. The ball'th usj completed Iplace between heating and compressing diesL and M, Fig. 5, whereby the ball is given'its nal form. The heat renders the Celluloid plastic and the compression thoroughly compacts the material of the casing as well as the guttakpercha cover C. The dies arepreferably provided with pits, whereby brambles or pebbles N are formed upon the ball.

`By rst welding the gutta-percha cover on the compressed core A', then overwinding saidshell with strips or ligaments of fibrous material compounded with plastic material, then subjecting the whole to heat and compression and maintaining vthe compression while the ball cools and the cover and casing harden I form a ball which is not only Very lively and liies a long distance when struck aha'rd blow, but which'is also practically rupture-proof. in the casing the ball is prevented'frorn be- Ying unduly sensitive when given a light blow by an implement, so that it is well adapted for putting If desired, the casing J may be omitted and other variations may be resorted to within the scope of my present improvements.

Having described my invention, `I claim- 1. A playin g-ball comprisinga wear-resisting cover and a distorted core of softprubber held under compression thereby; said core being distorted throughout in radial directions.

Owing to the presence of fabric IOO 2. A playing-ball comprising a solid rubber spherical shell and a cover of hard, wear-resisting material thereon; said rubber shell being in a state of collapse and held under compression by said casing.

3. A playing-ball comprising a cover of plastic material and a filling held under compression thereby; said filling consisting of a solidrubber spherical shell in a state of collapse.

4. A playing-ball comprising a cover which consists of welded segments of gutta-percha, and a filling held under compression by said shell; said filling consisting of a rubber spherical shell in a state of collapse but tending constantly to recover its normal form.

5. A playing ball comprising a rubber spherical shell in a state of collapse, and a cover holding said shell under compression; said cover being a compound of plastic material and fabric.

G. A playing-ball comprising a coverof plasfic material and a filling held under compression thereby; said filling consisting ot' a solidrubber spherical shell which is collapsed to such an extent as to form substantially a solid sphere.

7. A playing-ball comprising a cover consisting of welded segments-of plastic material, and a filling held under compression by said shell; said filling consisting ot' a rubber spherical shell collapsed` to such an extent to form a substantially solid sphere.

8. A playing-ball comprising a cover consisting of welded segments of gu'tta-percha, and a filling held under compression by said shell; said filling consisting of a rubber spherical shell collapsed to such an extent as to form a substantially solid sphere.

fl. A playing ball comprising a rubber spherical shell compressed to an extent to form a solid sphere, and a covering upon said sphere consisting of plastic material compounded with fabric.

10. A playing-ball comprising a wear-resisting cover and a distorted core of soft rubber held under compression thereby; said core being distorted throughout in radial directions, and forming a solid sphere.

1l. A playing-ball comprising a rubber sphere compressed in bulk and a shell thereon consisting of plastic material and fibrous material, the latter being continuously Wound in different directions and embedded in the plasl tic material.

sphere compressed in bulk, and a shell thereon, said shell comprising Welded segments of plastic material and a casing, the latter consisting of plastic material in which are embedded strips of fabric, and said stri ps being Wound continuously in dierent directions.

13. A playingball comprising a rubber sphere materially compressed in bulk, and a shell holding said sphere under compression; said shell including portions of gutta-percha and fabric.

14. A playingball comprising a rubber sphere materially compressed in bulk, and a shell holding said sphere under compression; said shell comprising gutta-percha,fabric and celluloid, the latter forming the periphery or facing of the ball.

15. A playingball comprising a rubber sphere materially compressed in bulk, a shell holding said sphere under compression, said shell consisting of welded segments of guttapercha, and a casing consisting of strips of Celluloid and fabric wound continuously in differentdirections and compressed upon said gutta-percha.
